Centrecoat Asbestos Roof Coating

Centrecoat Asbestos Roof Coating (ARC) is a high quality water based acrylic for the encapsulation of asbestos roof and corrugated cladding.

Best Uses

Centrecoat Asbestos Roof Coating has shown proven adhesion to a wide variety of difficult to paint substrates.

Centrecoat Asbestos Roof Coating contains zinc phosphate anti-corrosive pigmentation. Provides a tough, flexible, durable coating for exterior surfaces, and is also suitable for corrugated metal sheeting and Plastisol sheeting.

Ideally suited for encapsulating asbestos shingles and corrugated roof sheets on garages, porches and farm buildings. Also suitable for asbestos cladding found in agricultural environments. 

• Anti-corrosive zinc phosphate pigmentation
• Proven adhesion to a wide range of substrates
• Tintable
• Fast drying
• Early water spot resistance
• Tough, flexible and durable

Application

Remove loose flaky paintwork back to a firm edge. Ensure all surfaces are clean, dry and free from all contamination before abrading to give a surface with an adequate key. Particular attention should be applied to glossy substrates. Apply the material to a small test area to ensure there are no adverse reactions with the existing coating before painting. Failure to prepare the substrate adequately may result in poor intercoat adhesion, delamination of the coating and or other defects.

Do not apply or dry when the air or substrate temperature is below 5°C or in excess of 30°C otherwise film appearance and coating properties may be adversely affected. Surface temperature must also be a minimum of 3°C above dew point. Outdoors preparation, painting and drying should only be undertaken during good weather conditions and never when rain is imminent or on days when a drop in temperature could result in condensation forming on the paint during the initial drying period or overnight. Maximum recommended relative humidity for application and drying should preferably not exceed 80%.

Mix thoroughly before use. Best results will be achieved using a power mixer. Provided ready for use.

Airless Spray
Using a brush to provide a ‘strike coat’ on difficult to reach areas such as internal welds, rough spots, bolts or corners before application of the spray coat is a good method of ensuring adequate build is achieved. One even coat applied in parallel passes, overlapping 50% on each pass to avoid bare areas, pinholes or holidays, at the stated W.F.T. is satisfactory for most purposes. However, should additional coats be required for higher film builds or blast cleaned profiles, these should be applied wet on wet after the surface is touch dry. Thinning not required. Use 13 - 15 thou tip size at 120 - 140 at 1700 - 2000 psi. Overcoatable after 30 minutes minimum.

Brush / Roller
Apply by long haired brush or polyether foam roller with rounded edges. Care must be taken to ensure continuous wet edge to ensure uniform coat and prevent, “dragging”, of the coating during application. An addition of maximum 5% clean water may be added to aid application and increase wet edge time. Thin with maximum 5% clean water if required. Overcoatable after approx 3 hours at 20°C. May require 2 coats.
